. My invention relates to desks for typewriters or other similar machines, particularly to such a desk in which the typewriter or other machine is supported on a non-tiltable platform or table, and the objects of my invention are, first, to provide a desk of this class which is provided in and below its main top member with a passage extending substantially from front to rear, whereby a typewriter or other machine, positioned at the rear of the desk within and below a superstructure when not in use, may be easily pulled forwardly to the position desired for use; second, to provide a desk of this class having a stationary machine-supporting panel or member extending thefull length and width of the desk to provide a rigid construction for a desk of this class having its main top member partially cut away crossg0 wise, as in the conventional construction; third, to provide a typewriter desk having a typewriter-supporting panel extending the whole length and width of the desk, provid ing a rigid structure therefor and permitting 215 a single or double typewriter desk to be made with four legs only; fourth, to provide a superstructure for a desk of this class into which the removable portions or panels of the top and front side members of the desk may be positioned when the typewriter or other machine is adapted to be pulled out wardly for use; fifth, to provide a novel means, in a desk of this class, for limiting the outward movement of the shiftable machinesupporting platform and a novel means for varying the limit of said movement; sixth, to provide a novel means for retaining said shiftable machine-supporting platform in position after the same is pulled outwardly;

seventh, to provide a novel and dustproof desk for typewriters and other similar machines; eighth, to provide a novel means for a locking the removable panels of the top and front side members in position when the desk is closed; ninth, to provide a novelly constructed and operated mechanism for limiting and fixing the outward position of a shiftable machine-supporting platform; and, tenth, to provide a desk for typewriters and an other similar machines which simple and economical of construction, durable, and which. will not readily deteriorate or get out of order.

Vfith these and other objects in view as will appear hereinafter, my invention consists of certain novel features of construe tion, combination and arrangement of parts and portions, will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings and to the characters of reference thereon, which form a part of this application, in which:

Figure 1 is a front elevational view of my desk with certain parts and portions thereof broken away and in sections to facilitate the illustration; Figure 2 is a plan view thereof, also showing certain parts and portions broken away and in. sections to facilitate the illustration; Figure 3 is a sectional eleva tional view thereof taken thru 3-3 of Figure 1; Figure 4 is a fragmentary, sectional view in plan taken thru 4-4 of Figure 1; Figur 5 an enlarged fragmentary plan view showing the relation between the typewriter-supporting platform, the roller means and the platform limiting and retaining means; Figure 6 is a sectional, elevational View thereof taken thru 6-6 of Figure 5; and Figure 7 is another sectional, elevational View thereof taken thru 7'? of Figure 5.

Like characters of reference refer to similar parts and portions throughout the several views of the drawings.

My desk consists essentially of leg members 1, a top member 2, supported at the upper ends of said leg members and provided inter-- mediate its ends and at its front portion with a cut away portion 2, a rigid stationary typewriter-supporting panel 3, positioned bclowthe top member 2 and extending between said leg members and suported thereby, a superstructure 4, positioned at the rear portion of the top side of the top memher 2 and provided at its front side intermediate its ends with a large opening 4 a cover member 5 for said opening, a top panel 6 for the cut away portion in said top momher, a front side panel 7 for the opening in tha front side of the desk, and a shiftable 10c typewritersupporting platform 8 reciprocally'mounted on the supporting panel 3 within the passage provided in the desk. When embodying my invention in a single type typewriter desk, that is, in one having drawers on one side only, one of the drawers 9 is positioned atone side between the top member 2' and'the member 8, and the other drawers are suspeded from the member -3'and one of the leg members as shown bestin Figure 1.

At the sides of the top member 2 forming the opening 2 therein are provided ledges 2 7 upon which are adapted to be supported corresponding off-set portions at the side edges of thetop panel 6. The front ends of the ledges 2 are cut away as shown best by dotted lines in Figure 2, to'receive the downwardly extending apron 6 at the front edge of the top panel 6. Between the supporting ledges 2 and the sides of the top member 2 forming the opening therein are provided grooves 2 for catching dust, On the under sides of the off-set portions at theside edges of the top panel 6 is secured felt '11 for sealing the typewriter compartment in the desk. At the side edges of the under sides ofthe panel member '6 are'secured' to ancl retaininmmembers 12 for retaining the to panel 6 in position. Thesemembers 12 are adapted to be retained in longitudinal grooves'2 at the sides of the ledges 2 The ends of the removable front side panel Tar-e provided with vertical grooves 7 which are adapted to receive corresponding tenons '13. atthe edges of the front side members 13.

The front edgeof the panel 3 is rabbeted, as indicated by 3 in Figure '3, to receive the lower edge of the removablefront side panel t. The joints between the panel 3 and top panel'o'and the removable front side panel '7 .are also sealed by felt 1 1, as indicated in Figure of the dr w ng The over memberor door 5, adapted to enclose the opening l at the front side of the superstructure fl, is provided at its sides near its upper edge with pins .5 Which-are hinged atthe one end of and adapted to Slideinwardly in grooves 4 at the upper portion of the sides of the com- .partment in the superstructure, as shown best in Figure 3, to permit the door 5't0he raised about its pivotal mountingand partially inse'rted edgewise at the upperportion of the superstructure, as shown in Figure 1. This door when inserted edgewise into the superstructure rests on a horizontal partition" 14.

Atthe inneredge of the top'panelfi is pro- 'vided an upwardly extendingledge 6 which is adapted tobe engagedby the loweredge of'the door 5, when the same is closed. -When this doo -r 5 is locked by means of alock or bolt means, asindicated by 15 in Figures 1 and2, when in a closedposition, the panels 6 and 7 cannotbe removed. The inner side of the door 5 is also preferably covered near its screws 22 near their rear ends.

edges with felt 11 to seal the interior of the superstructure from dust.

In the superstructure 4, below the partition 14, extending horizontally therein, is provided another horizontal partition 16, spaced m from the partition 14. In this space between the partitions 14: and 16 are adapted to be positioned the top panel 6 and the front side panel '7, when the desk is opened and in use,

as shown by dotted lines in Figures 1 and 3.

The panels 6 and 7 are separated in said space by a vertical partition 17.

At the lower side portions of the passage, formed within the desk by the cut away portions in the table top member 2 and the front side member 13, are positioned guide IDQHIlJOlS 18 which may be secured to the stationary typewriterfsupporting panel 3. Between theseguide members 18 is reciprocally mounted the shiftable typewriter platform 8 which is provided with a plurality of rollers 19. These rollers 19 consist of frames 19 inserted and secured into the platform 8, and roller members 19" revolubly mounted therein in such a manner as to raise the platform 8 00 wardly extending portions 19 at their outer 05 edges. These portions 19 are adapted to engage inwardly extending lugs 20 and 20, respectively at the rear and front ends of the typewriter platform stop and retaining members 20 reciprocally mounted at the upperioo sides of the guide members 18 by means of the screws 21 at their front ends and thumb At the top sides ofthe guide members 18 are provided a plurality of tapped holes 18 into which the thumb screws 22 are adapted to be screwed for var ously limiting the outward movement of the typewriter platform 8. Thus it will be seen that when the platform 8 is pulled outwardly the upwardly extending portions 19 no of the forwardly positioned roller frames will engage the inwardly extending lugs 20 of the 'members 20, forcing the same outwardly to the positlon shown by dotted lines, the outward pos tions of the members 20 depending upon the position of the thumb screws 22 relatlvely to the guide members 18. The lugs 20 of the members 20 are adapted to be engaged by the portions 19 when the platform 8 is pushed inwardly, thus forcing the members 2Qinwardly. It will be noted that the members 20 extend inwardly over the, platform 8 so that said members also perform the function of holding the platform 8 downwardly against the stationary supporting panel 3.

In the upwardly extending portions 19 of the forwardly positioned roller frames 19 are revolubly mounted spindles 23 which are provided with eccentric discs 24 as shown best in Figures 6 and 7. These eccentric discs 24 are rotatably mounted in annular portions 25 of the platform raising plungers 25 which are reciprocally mounted in the roller frames and also thru the typewriter-supporting platform 8. The spindles 23 are provided with levers 26 which are adapted to raise and lower the plnngers 25 depending upon the position thereof relatively to the platform, the position of the lever 26 in Figure 7 of the drawings showing the plunger 25 forced down warly for raising the front rollers 19 of the platform 8 from the supporting panel 3. At both sides of the outer or front portions of the stationary member 3 are provided plates 27 having a plurality of spaced counter-sunk holes 27 which are adapted to receive the ends of the plungers 25 as shown in Figure 7. The spacing between the holes 27 in the plates 2'? is preferably less than the spacing of the tapped holes 18 in the guide members 18 so as to provide a greater Variation of adjustment for the position of the typewriter. When the levers 26 are rotated about the supports 19 to the position shown in Figure 4, the plungers 25 are raised from the plates 27 permitting the front rollers to engage the panel 3, thus permitting the platform 8 to be shifted backwardly.

It is obvious from this construction, as illustrated in the drawings and disclosed in the foregoing specification, that there is provided a desk for typewriters or other similar machines as aimed at and set forth in the objects of the invention, and though I have shown and described a particular construction, combination and arrangement of parts and portions, I do not wish to be limited to this particular construction, combination and arrangement, but desire to include in the scope of my invention the construction, combination and arrangement substantially as set forth in the appended claims.

Having thus described my invention, what it claim as new and desire to secure by Letters Patent is: r

1. In a desk, a platform supporting panel member, a shiftable platform reciprocally mounted on said panel member, an adjustable and shiftable stop means mounted on said panel member for retaining said platform thereagainst and for limiting the outward position of said platform, and a lever means mounted on said platform and engageable with said panel member for raising the forward end of said platform from said panel member when the same is shifted to any desired outward position.

2. in a desk structure, a panel member, a platform reciprocally mounted above said panel member, guide means for said platform, and an adjustable and shiftable slide mounted on said guide means and overlapping one side of said platform, means for releasably securing said slide to said guide means, said slide retaining said platform in a downward position and forming stop means for limiting the outward position thereof, said slide being shiftable independently of or by said platform.

3. In a desk structure, a panel member, a platform reciprocally mounted above said panel member, guide means for said platform, an adjustable and shiftable means mounted on said guide means overlapping the side of said platform for retaining said platform in a downward position and forming stop means for limiting the outward position thereof, and a lever and eccentric means for raising the forward end of said platform when the same is shifted to its outward position.

In testimony whereof, I have hereunto set my hand at San Diego, California, this 29th day of September, 19%.
